How To Recover NTFS Encrypted Files?

Hey there, I'm new to the board, and hopefully not posting in the wrong section.

Ok, here's the deal... I got 2 HDs, both NTFS. C was for Windows XP and progs, D for my personal files.
Some folders on D were encrypted (with that right click-> properties -> advanced... -> encrypt contents option) so that they would only be accessible from my password protected account. I then formatted C, to reinstall windows and everything. now i can access those folders anymore.

I've looked everywhere and tried to recover those files using various apps available on the net, but nothing can be recovered because i formatted, and the encryption keys were lost.

Do any of you guys know how i could recover my files? I lost all the source code to all my programming projects!
